Description

Technical Field

[0001] This invention relates to the field of harmless treatment devices, and in particular to a harmless treatment device for medical waste gas samples. Background Technology

[0002] Medical waste gas samples (such as waste blood, body fluids, tissue samples, and disposable containers used to hold these samples) carry a large number of pathogenic microorganisms (bacteria, viruses, fungi, etc.). Improper handling can easily lead to cross-contamination of the environment, occupational exposure of medical personnel, and public health safety risks. Currently, the mainstream methods for the harmless treatment of medical waste gas samples mainly include high-temperature steam sterilization, chemical disinfection, and incineration. However, existing technologies have the following key problems:

[0003] Most devices use a "stacking" method, where samples are piled up at the bottom of the processing chamber. High-temperature steam can only act on the surface samples, and the internal samples are not thoroughly sterilized due to insufficient steam penetration, leaving some pathogenic microorganisms behind. In addition, some devices do not have a steam flow optimization structure, resulting in "dead zones" in the contact between steam and samples.

[0004] The existing devices mostly have a fixed integrated support structure. After treatment, the residue is easy to adhere to the cavity wall and the surface of the support. Disassembly and cleaning require disassembling multiple parts, which is cumbersome and can easily cause secondary pollution. Some devices have unreasonable sealing structure design. Steam leakage not only reduces thermal efficiency, but may also cause pathogenic microorganisms to spread with the steam. Summary of the Invention

[0005] Based on this, it is necessary to provide a medical waste gas sample harmless treatment device to address the above-mentioned technical problems. Through the design of "layered support and staggered through-holes", the steam dead zone of the traditional "stacking" treatment is broken. The steam forms a "winding flow" in the second cavity, which fully contacts each layer of sample, resulting in a higher inactivation rate of pathogenic microorganisms and solving the risk of residue.

[0006] This invention provides a device for the harmless treatment of medical waste gas samples, comprising:

[0007] A processing box is fixed on a steam base. The processing box has a first cavity and a second cavity inside. The first cavity is located below the second cavity. The surface of the processing box has an opening that faces the junction of the first cavity and the second cavity.

[0010] The second tray is installed along the opening at the junction of the first cavity and the second cavity;

[0013] In one embodiment, two side positioning blocks are provided on the outer surface of the cylinder. The two side positioning blocks are respectively located on both sides of the opening. A positioning groove is formed on the opposite side of the two side positioning blocks. The top surface of the positioning groove is on the same plane as the bottom surface of the second semi-ring plate, the bottom surface of the positioning groove is on the same plane as the top surface of the first semi-ring plate, and the bottom surface of the side positioning block is on the same plane as the bottom surface of the opening.

[0014] In one embodiment, one end of the second tray is configured as a semi-circular plate structure, and the other end is configured as a rectangular plate structure. One end of the semi-circular plate structure is engaged between the first semi-ring plate and the second semi-ring plate, and one end of the rectangular plate structure is engaged in the positioning groove. A connecting plate is also provided between the two side positioning blocks. The upper surface of the connecting plate is on the same plane as the bottom surface of the positioning groove. The surface of the second tray is provided with a plurality of second vent holes.

[0015] In one embodiment, the adapter includes a base plate, a top plate, and a first annular plate; the base plate is disposed at the top of the cylinder, the top plate is located directly above the base plate, the inner ring height of the first annular plate is higher than the outer ring height, and the base plate and the top plate are connected through the first annular plate.

[0016] In one embodiment, both the feeding pipe and the connecting pipe are located between the bottom plate and the top plate, and both ends of the feeding pipe and the connecting pipe respectively penetrate the top plate and the bottom plate. The feeding pipe is used for discharging waste gas samples, and the connecting pipe is used for venting steam and allowing flushing water to enter.

[0017] In one embodiment, the support member includes a first support plate, a hemispherical plate, and a first fastener; the flat end of the hemispherical plate faces downward, and the hemispherical plate is fixed to the driving end of the driving member by the first fastener; a plurality of first support plates are arranged in a ring array at the flat end of the hemispherical plate; a plurality of first vent holes are provided on the first support plate; a through opening is formed between two adjacent first support plates; and the vertically adjacent through openings are staggered from each other in the longitudinal direction.

[0018] In one embodiment, a second annular plate is fitted onto one end of one of the first support plates away from the hemispherical plate. The inner ring of the second annular plate is connected to one end of the first support plate, and the outer ring of the second annular plate is bent upward and movably fits against the inner surface of the cylinder.

[0019] In one embodiment, the cover includes an arc-shaped plate and a stop plate; the surface of the arc-shaped plate is attached to the outer surface of the cylinder to close the opening; the arc-shaped plate is located directly above the connecting plate; the bottom surface of the arc-shaped plate is connected to the stop plate; and the stop plate is used to abut against one end of the rectangular plate structure of the second support plate.

[0020] In one embodiment, elongated holes are provided at both ends of the surface of the arc-shaped plate, the elongated holes are arranged longitudinally, a positioning rod is fixed on the surface of the cylinder, the positioning rod is inserted into the elongated hole, a second fastener is installed at the end of the positioning rod for making the arc-shaped plate fit against the surface of the cylinder, and a handle is provided in the middle of the arc-shaped plate.

[0021] The aforementioned medical waste gas sample harmless treatment device fixes the treatment box onto a steam base, ensuring a clear separation between the first and second cavities. By longitudinally moving the cover, the opening on the surface of the treatment box directly opposite the junction of the two cavities is opened. The second tray is then installed along the opening to the junction of the two cavities. The cover is closed and sealed. Before starting the device, the medical waste gas sample is placed into the second cavity via an adapter. The sample is guided by the adapter and falls onto a support within the second cavity. The steam base is then activated, allowing high-temperature steam to enter the first cavity. Simultaneously, the drive unit on top of the adapter is activated, causing the drive end of the drive unit to move the support within the second cavity synchronously. Steam enters the second cavity through the gaps in the second tray. Because the through-holes of adjacent support units are longitudinally intersecting, the steam must flow around the support units to fully contact each layer of the sample, achieving high-temperature inactivation. After treatment, the steam base and drive unit are closed. After the device cools down, the cover is longitudinally moved to open the opening, the second tray is removed, and the treated residue is collected, completing a single treatment cycle. Through a layered support and staggered through-hole design, the steam dead zones of traditional "stacking" processing are broken. Steam forms a "winding flow" in the second cavity, making full contact with each layer of samples, resulting in a higher inactivation rate of pathogens and eliminating the risk of residue. The layered design of the first and second cavities allows steam to permeate upwards from the lower first cavity, conforming to the natural rising characteristics of hot steam and resulting in higher thermal efficiency. The cap and the second tray work together to achieve an opening seal, preventing steam leakage and the spread of pathogens, reducing operational risks. Samples are placed through the top transfer seat without having to open the entire processing box, reducing exposure. Residue is collected through the opening and the second tray without disassembling the internal structure, resulting in shorter single cleaning time. Attached Figure Description

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] The following is combined Figures 1 to 8 This invention describes a medical waste gas sample harmless treatment device.

[0035] like Figures 1 to 3As shown, in one embodiment, a medical waste gas sample harmless treatment device includes a treatment box 200, an adapter 300, multiple support members 500, a second tray 600, and a cover 700. The treatment box 200 is fixed on a steam base 100. The treatment box 200 has a first cavity 270 and a second cavity 280 inside, with the first cavity 270 located below the second cavity 280. An opening 211 is provided on the surface of the treatment box 200, directly facing the junction of the first cavity 270 and the second cavity 280. The adapter 300 is installed on the top of the treatment box 200, and the waste gas sample is placed into the treatment box through the adapter 300. Inside the second cavity 280, a driving member 400 is provided on the top of the adapter 300, and the driving end of the driving member 400 extends through the second cavity 280; multiple support members 500 are distributed longitudinally at intervals in the second cavity 280 and fixed to the driving end of the driving member 400. Multiple through holes 540 are provided on the support members 500 in a ring array, and the through holes 540 of two adjacent support members 500 are staggered in the longitudinal direction; a second tray 600 is installed along the opening 211 at the junction of the first cavity 270 and the second cavity 280; a cover 700 is longitudinally movably installed on the surface of the processing box 200 to close the opening 211.

[0036] The aforementioned medical waste gas sample harmless treatment device fixes the treatment box 200 onto the steam base 100, ensuring a clear separation between the first cavity 270 and the second cavity 280. By longitudinally moving the cover 700, the opening 211 on the surface of the treatment box 200 facing the junction of the two cavities is opened. The second support plate 600 is then installed along the opening 211 to the junction of the two cavities. The cover 700 is closed and sealed. Before starting the device, the medical waste gas sample is placed into the second cavity 280 via the adapter 300. The sample is guided by the adapter 300 and falls onto the support 500 within the second cavity 280. The steam base 100 is then activated, releasing high-temperature steam. The steam enters the first cavity 270, and simultaneously activates the drive unit 400 on top of the adapter 300. The drive end of the drive unit 400 drives the support unit 500 in the second cavity 280 to move synchronously. Steam enters the second cavity 280 through the gap of the second tray 600. Because the through-holes 540 of adjacent support units 500 are longitudinally intersected, the steam needs to flow around the support unit 500 to fully contact each layer of sample and achieve high-temperature inactivation. After the treatment is completed, the steam base 100 and the drive unit 400 are closed. After the device cools down, the cover 700 is moved longitudinally to open the opening 211, the second tray 600 is taken out, and the treated residue is collected to complete a single treatment. The design of "layered support and staggered through-holes 540" breaks the dead zone of steam in traditional "stacking" processing. Steam forms a "winding flow" in the second cavity 280, which fully contacts the samples in each layer, resulting in a higher inactivation rate of pathogens and eliminating the risk of residue. The layered design of the first cavity 270 and the second cavity 280 allows steam to permeate upward from the lower first cavity 270, which conforms to the natural rising characteristics of hot steam and has higher thermal efficiency. The cover 700 and the second tray 600 work together to seal the opening 211, preventing steam leakage and the spread of pathogens and reducing operational risks. Samples are put in through the top adapter 300 without having to open the entire processing box 200, reducing exposure. Residue is collected through the opening 211 and the second tray 600 without having to disassemble the internal structure, resulting in shorter cleaning time per cycle.

[0037] like Figure 4 and Figure 5 As shown, in one embodiment, the processing box 200 includes a cylindrical body 210, a first semi-annular plate 220 and a second semi-annular plate 230; an opening 211 is formed on one side of the inner surface of the cylindrical body 210, the first semi-annular plate 220 and the second semi-annular plate 230 are disposed on the other side of the inner surface of the cylindrical body 210, the first semi-annular plate 220 is located below the second semi-annular plate 230, and there is a gap between the two.

[0038] Specifically, by replacing the traditional integral partition with a semi-ring plate structure, the first cavity 270 and the second cavity 280 are kept independent while providing a precise "embedded" installation position for the second support plate 600. The semi-ring plate structure is lighter than the integral partition, reducing the overall load on the processing box 200. At the same time, the separate design of the semi-ring plate and the cylinder 210 facilitates partial replacement and reduces maintenance costs.

[0039] In one embodiment, two side positioning blocks 240 are provided on the outer surface of the cylinder 210. The two side positioning blocks 240 are located on both sides of the opening 211. A positioning groove 241 is provided on the opposite side of the two side positioning blocks 240. The top surface of the positioning groove 241 is on the same plane as the bottom surface of the second semi-ring plate 230, the bottom surface of the positioning groove 241 is on the same plane as the top surface of the first semi-ring plate 220, and the bottom surface of the side positioning block 240 is on the same plane as the bottom surface of the opening 211.

[0040] Specifically, the planar alignment design of the positioning groove 241 and the semi-annular plate ensures that the installation deviation of the second support plate 600 is controlled within a certain range, ensuring that the second support plate 600 fits completely with the cavity interface, preventing steam leakage from the gap and significantly enhancing the sealing performance. The side positioning block 240 not only provides double-sided support for the second support plate 600, but also enhances the structural strength of the opening 211 of the cylinder 210, preventing deformation of the opening 211 of the cylinder 210 after long-term use and extending the service life of the device. The "guided" design of the positioning groove 241 allows the second support plate 600 to be directly snapped into place without additional calibration tools, shortening the installation time and improving operational efficiency.

[0041] In one embodiment, one end of the second support plate 600 is configured as a semi-circular plate structure, and the other end is configured as a rectangular plate structure. One end of the semi-circular plate structure is engaged between the first semi-ring plate 220 and the second semi-ring plate 230, and one end of the rectangular plate structure is engaged in the positioning groove 241. A connecting plate 250 is also provided between the two side positioning blocks 240. The upper surface of the connecting plate 250 is on the same plane as the bottom surface of the positioning groove 241. A plurality of second vent holes 610 are provided on the surface of the second support plate 600.

[0042] Specifically, the second vent 610 is evenly distributed, resulting in a higher steam throughput and ensuring that the high-temperature steam from the first cavity 270 can efficiently enter the second cavity 280, avoiding incomplete local treatment caused by steam blockage. The second tray 600 serves as a "pull-out" residue collection carrier, which can be directly pulled out for cleaning after treatment, avoiding secondary pollution caused by manual cleaning of the cylinder 210. Furthermore, its semi-circular structure fits the inner wall of the cylinder 210, eliminating dead corners for residue residue. The combined structure of "semi-circular, rectangular, and connecting plate 250" improves the fit between the second tray 600 and the treatment box 200, eliminating the risk of displacement during treatment and significantly enhancing structural reliability.

[0043] In one embodiment, the adapter 300 includes a base plate 310, a top plate 320, and a first annular plate 330; the base plate 310 is disposed at the top of the cylinder 210, the top plate 320 is located directly above the base plate 310, the inner ring height of the first annular plate 330 is higher than the outer ring height, and the base plate 310 and the top plate 320 are connected through the first annular plate 330.

[0044] Specifically, the top plate 320 and the bottom plate 310 provide "double-layer fixation" for the drive component 400 to prevent the support component 500 from shifting due to the shaking of the drive component 400, thus ensuring the stability of the processing.

[0045] In one embodiment, the feeding pipe 340 and the connecting pipe 350 are both located between the bottom plate 310 and the top plate 320, and both ends of the feeding pipe 340 and the connecting pipe 350 respectively penetrate the top plate 320 and the bottom plate 310. The feeding pipe 340 is used for the delivery of waste gas samples, and the connecting pipe 350 is used for the discharge of steam and the entry of flushing water.

[0046] Specifically, the feeding tube 340 and the connecting tube 350 are functionally independent, completely separating sample placement from steam discharge and flushing water introduction. This prevents steam from carrying pathogens into the feeding tube 340 or from the flushing water mixing with the sample, reducing the risk of cross-contamination. The steam discharge function of the connecting tube 350 prevents excessive pressure within the cavity, and the recovered steam can be reused. The flushing water is precisely introduced through the connecting tube 350, resulting in higher cleaning coverage. Cleaning can be completed without disassembling the support component 500. The dedicated feeding tube 340 prevents contact with the outside environment during sample placement, complying with the "closed operation" standard for medical waste gas treatment and protecting medical personnel from the risk of exposure to pathogens.

[0047] like Figure 7 and Figure 8 As shown, in one embodiment, the support member 500 includes a first support plate 520, a hemispherical plate 530, and a first fastener 550; the flat end of the hemispherical plate 530 faces downward, and the hemispherical plate 530 is fixed to the driving end of the driving member 400 by the first fastener 550. A plurality of first support plates 520 are arranged in a ring array at the flat end of the hemispherical plate 530. A plurality of first vent holes 521 are provided on the first support plate 520, and a through opening 540 is formed between two adjacent first support plates 520. The vertically adjacent through openings 540 are staggered from each other in the longitudinal direction. A plurality of third vent holes 531 are provided on the surface of the hemispherical plate 530.

[0048] Specifically, the staggered through-hole design 540 allows steam to form a "winding upward" path within the second cavity 280, eliminating steam dead zones and extending the contact time between the sample and steam to several times that of traditional devices, resulting in a higher inactivation rate of pathogenic microorganisms. The arc-shaped structure of the hemispherical plate 530, combined with rotation, ensures that the sample is evenly dispersed on the first support plate 520, increasing the steam contact area of ​​a single sample and significantly improving processing efficiency. The detachable design of the first fastener 550 allows the support component 500 to be disassembled and replaced individually. If the first support plate 520 or the hemispherical plate 530 is damaged, there is no need to replace the entire drive assembly, reducing maintenance costs.

[0049] In one embodiment, a second annular plate 510 is fitted onto one end of a plurality of first support plates 520 away from the hemispherical plate 530. The inner ring of the second annular plate 510 is connected to one end of the first support plate 520, and the outer ring of the second annular plate 510 is bent upward and movably fits the inner surface of the cylinder 210.

[0050] Specifically, the second annular plate 510 prevents samples from falling into the gap, avoiding "missed" residues and ensuring that all samples are treated harmlessly, thus improving the processing qualification rate; the annular plate adheres to the inner wall of the cylinder 210 to reduce steam leakage, improves the steam utilization rate in the second cavity 280, reduces heat loss, and significantly reduces processing energy consumption; the second annular plate 510 can prevent sample residues from directly contacting the inner wall of the cylinder 210, avoiding corrosion or contamination of the cylinder 210 caused by residue adhesion, and reducing the cleaning frequency of the cylinder 210.

[0051] like Figure 6 As shown, in one embodiment, the cover 700 includes an arc-shaped plate 710 and abutment plate 740; the surface of the arc-shaped plate 710 is in contact with the outer surface of the cylinder 210 for closing the opening 211, the arc-shaped plate 710 is located directly above the connecting plate 250, and the bottom surface of the arc-shaped plate 710 is connected to the abutment plate 740, which is used to abut against one end of the rectangular plate structure of the second support plate 600.

[0052] Specifically, the "curved surface fit" design of the arc plate 710 and the outer surface of the cylinder 210 increases the sealing area compared to the flat cover 700, and reduces the amount of steam leakage at the opening 211; the abutment action of the abutment plate 740 can prevent the second support plate 600 from shifting upward during the process, ensuring the fit between the second support plate 600 and the cavity interface, and preventing steam from leaking from below the second support plate 600; the curved structure of the arc plate 710 has no sharp edges, reducing the risk of scratches during operation; at the same time, the cover 700 can be opened and closed simply by moving it up and down, which is highly convenient.

[0053] In one embodiment, the arc plate 710 has elongated holes 711 at both ends of its surface, the elongated holes 711 are arranged longitudinally, a positioning rod 260 is fixed on the surface of the cylinder 210, the positioning rod 260 is inserted into the elongated hole 711, a second fastener 720 is installed at the end of the positioning rod 260, which is used to make the arc plate 710 fit against the surface of the cylinder 210, and a handle 730 is provided in the middle of the arc plate 710.

[0054] Specifically, the engagement of the positioning rod 260 and the elongated hole 711 restricts the lateral displacement of the arc-shaped plate 710, keeping the movement deviation of the cap 700 within a certain range, avoiding sealing failure due to displacement, and improving the operational error tolerance rate; the tightening action of the second fastener 720 makes the arc-shaped plate 710 fit more closely to the outer surface of the cylinder 210, ensuring that the cap 700 does not loosen during processing, and significantly enhancing the sealing reliability; the design of the handle 730 allows a single person to complete the movement operation of the cap 700; the engagement of the positioning rod 260 and the elongated hole 711 prevents the cap 700 from falling off, avoiding the risk of accidental fall.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
